NCAA Softball Tournament is set to start on Friday, May 16 with 64 teams chasing the ultimate prize. The Oklahoma Sooners have won four National Championships in a row, and look to extend their record-setting streak to five.

Among the five is Cori McMillan, who has a nation-leading 30 homers to go with 61 RBIs for Virginia Tech. Tennessee’s Karlyn Pickens has thrown the fastest pitch ever recorded by a college softball player.

OU fell behind 6-1 to Arkansas in the third inning of last Friday’s SEC tournament semifinal, got to within 6-5 by the sixth, then won 8-6 on Garcia’s walk-off three-run homer. It was the biggest comeback in SEC tourney history. The next day’s championship game against Texas A&M was rained out and the teams were named co-champions.
